SAVANNAH, Ga. (WJCL) -- Nearly a dozen people are facing felony drug charges following an undercover drug operation at a Savannah concert.

Chatham-Savannah Counter Narcotics Team (CNT) agents and other officers attended the Widespread Panic concert held at the Savannah Civic Center Friday night. Undercover agents made purchases of various forms of controlled substances including heroin and LSD. Agents also seized a cylinder containing nitrous oxide after observing persons purchasing balloons filled with the gas. Eight people were arrested on felony drug charges and transported to the Chatham County Detention Center. Money and a vehicle were also seized during the operation.

Local, state and federal law enforcement agencies came together in an effort to keep drugs out of the concert area. The Chatham County Sheriff's Office and Savannah-Chatham Metropolitan Police Department also assisted in the operation.

The arrests made in this operation are separate from any additional arrests that may have been made by other law enforcement agencies.
